5. Maintenance
Proper maintenance ensures the longevity and smooth operation of your Schlage ND10S ATH 626 Passage Lever Lockset.
- Cleaning: Clean the exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- Lubrication: Periodically apply a small amount of silicone-based lubricant to the latch bolt mechanism to ensure smooth operation. Do not use oil-based lubricants, which can attract dust and debris.
- Inspection: Regularly inspect all screws and fasteners to ensure they are tight. Loose components can affect performance and durability.
- Corrosion Resistance: The lockset features zinc plating for enhanced corrosion resistance, reducing the need for extensive anti-corrosion treatments.
